there is a minor change in page.tpl.php.
please read the readme file in "/upgrade/"

"/themes/YOUR_THEME_FOLDER/page.tpl.php" with a text editor, replace:
echo $tpl_vars['application'];
with
show_content();

I can not find (echo $tpl_vars['application'];)
in page.tpl.php

also page.tpl.php is in every theme folder and pointing to defualt theme.

I want biglogo to work.help plz

well.. I think you can download the "black" theme, and enable it.
Once it is enabled successfully, copy the "style.css" and all image files from your "biglogo" folder to "black" folder.
I'm not sure is it work, so please test this in your localhost.

black theme works but can't hide menu across the top.

What did you mean "hide menu across the top". Please let me know the details and I will tell you how to customize it.

Black theme has navagation menu links across the top, can not use //hidemenu in welcome_page.php to hide. A guest can click any link without having to sign up. Guest MUST sign up frist before they can access site.

I can not get biglogo to work is my problem, can I use 2.3 theme on 2.5? upgrade? the upgrade put a page.tpl.php file in theme folder. now all themes are the same. Each theme have same (page.tpl.php) but page.tpl.php is for default theme.

No they are not same. You need to enable a new theme to see the difference.

are you part of the jcow team? or just another customer trying to help out? I really need stans help. my themes is not working. I can not set it to biglogo, and when I do, it show defult theme not biglogo.

I'm a new (forum)supporter from Jcow team. The "biglogo" is a theme for Jcow 2.3, you can not use it directly for Jcow 2.4/2.5

If you copied a page.tpl.php from "default", you need to edit the page.tpl.php to replace "themes/default" to "themes/biglogo".
